Answer:
The key is finding a common # on the bottom (aka: a common 'denominator')
once you do this, you can easily add and subtract them!
Step-by-step explanation:
EX:
1/2 + 2/3 = ?
<u>*EASIEST TRICK!!*</u>
take your 2nd denominator: (3) and multiply it by the entire (1st fraction): 1/2
<em>(when we MULTIPLY fractions, it is easy as pie, we can just multiply across the top and across the bottom) in this case, we will multiply both top and bottom by the 2nd denominator (3)</em>
(1 x 3)/(2 x 3) = 3/6 <em>(3/6 is another way of saying 1/2, so we're good!)</em>
now take the 1st denominator (2), and multiply the entire 2nd fraction by that:
(2 x 2)/(3 x 2) = 4/6
<em>now we have 6 on the bottom of both! time for the magic:</em>
3/6 + 4/6 = 7/6
but wait! (that means we have 7 slices of a 6-piece pie! ...so we <em>actually </em>have, 1 full (6-piece pie) and 1 slice leftover! <em>(awww yeeea)</em>
<em>so, 7/6</em><em> --> </em><em>1 </em><em>(full pie) </em><em>1/6 </em><em>(leftover!)</em>
<u><em>now to put it all back together:</em></u>
1/2 + 2/3 = 1 & 1/6
The answer to this question is H. I hoped I helped you.
1) You can understand and work with other people's results, you can cooperate with other people in production of goods and check their experiments to see if they are correct.
2) It reduces errors since many people work towards specifying it exactly.
Answer:
Step-by-step explanation:

Multiply the whole equation by 2

24*4x - 5*24 + 2 = 20
96x - 120 + 2 = 20
96x - 118 = 20
Add 118 to both sides
96x = 20 +118
96x = 138
Divide both sides by 96
x = 138/96 = 23/16
